This commit fixes issue #1338 by removing duplicate content blocks that
were appearing 3-4 times on the page.
Changes:
1. README.md:
- Removed duplicate "Branch Protection & Review Policy" section (lines 121-134)
- Removed duplicate "Running Locally" section (lines 149-167)
- Kept the detailed "Branch Protection & Review Policy" section at the top
- Kept the first "Running Locally" section with all content
2. POLICY.md:
- Consolidated duplicate content into single cohesive policy
- Merged two "Branch Protection Rules" sections
- Merged two "Default Reviewer" sections
- Merged two "Acceptance Criteria" sections
- Added "Enforcement" and "Notes" sections from second half
The duplicate content was likely caused by a bad merge or template duplication.
This cleanup ensures each section appears only once while preserving all content.
Closes#1338
